How many hours of sleep do you need?


INFOGRAPHY – Researchers at the National Sleep Foundation have estimated the ideal daytime sleeping time for each age group.


If some people overflow with energy after a 4-hour night and others feel ineffective at the office because the alarm clock rang 20 minutes too early, it’s just because we are not all equal before sleep. The National Sleep Foundation (NSF), a US organization to promote sleep education, released this week the results of a survey to determine the number of daily sleep hours adapted to everyone’s well-being.
After analyzing 300 scientific publications, 18 scientists from the NSF Expert Committee, including specialists from the American Academy of Pediatrics, the American Society of Geriatrics, and the American Neurology Association, voted To establish a chart showing the appropriate amount of sleep at each stage of life.
Not surprisingly, newborns (0-3 months) require the highest rate of sleep per day: between 14 and 17 hours are recommended. Adolescents (14-17 years) need to sleep 8 to 10 hours per night. Adults (26-64 years), between 7 and 9 hours, and those aged 65 and over, have somewhat higher needs: 7 to 8 hours of daily sleep are recommended by researchers.

Sleep Hours

“It’s important to look at these numbers because we spend an average of one-third of our lives asleep and our health depends largely on our quality and our sleeping time. This remains a key issue that affects our lifespan, “says Charles Czeisler, chairman of the National Sleep Foundation. “Although our research does not allow us to indicate an exact length of sleep for each age, our new table reveals a golden rule on which all experts agree,” he said.

“Each case is unique”

However, “If you sleep well and feel good, keep up with that pace,” says Max Hirshkowitz, a specialist sleeping physician at Harvard and NSF president, “Every case is special, it’s important to pay attention to your needs. But if you follow the recommended sleeping times for your age group and feel tired throughout the day, it may be a sign that your sleep conditions or your environment are not appropriate. ”

In France, a survey carried out in 2014 by Opinion Way on behalf of the National Institute of Sleep and Vigilance (INSV) revealed that 36% of workers sleep less than 6 hours on weekdays. Recent studies have however highlighted the harmful effects of a lack of sleep: obesity, anxiety or even increased risk of developing Alzheimer’s disease. So tonight, herbal tea and in bed.
